Objective and scope, definitions

The present Part 10 of the guideline VDI/VDE/DGQ/DKD 2622 is valid for the calibration of high-frequency field strength measuring instruments in unmodulated high-frequency fields of a single frequency above 9 kHz. It should be used in conjunction with Part 1 "Fundamentals" and Part 2 "Uncertainty of Measurement" of this guideline. High-frequency field strength measuring instruments of the type considered here are primarily used for measurements in general public protection and occupational safety, as well as for setting the field strength in tests of electromagnetic compatibility (EMC).

Part 10 does not hold for the calibration of field strength measuring instruments or systems based on measuring antennas in conjunction with RF-level measuring devices (power meters, receivers, spectrum analyzers), neither for field strength measuring instruments for pulsed (transient) fields.

Depending on the design of the RF-field strength meter, the sensor picks up the electric and/or magnetic component of the electromagnetic field. Unless individually defined, the concept field strength in the following text is synonymous with the electric field strength (E), the magnetic field strength (H), or (particularly in the microwave range) the power flux density (energy flux density), i.e. the time-averaged Poynting vector (S). Within the context it will be clear whether the respective field vector, the amplitude of a spatial component or the (time-averaged) absolute value or the effective value is meant.
